11 Claims.

This invention relates to syringes and more particularly to syringes employable by females for sanitary douching purposes.

One of the objects of the invention is to produce an improved syringe nozzle for female douche use.

Another object is to produce a syringe nozzle which will permitrotation of spray orifices during use.

A further object is to embody in a syringe nozzle for female use a rotatable member which will permit the opening of folds and crevices in the membrane and the simultaneous washing thereof by moving jets of cleansing liquid.

Yet a further object is to provide a syringe nozzle with a rotatable spraying end portion which can be rotatable from the exterior of a cavity durin douching.

Still a further object is to produce an improved means for rotating a rotatable member on the end of a syringe nozzle by a flexible shaft in order to permit the rotatable member to be mounted at the end of a curved nozzle tube.

Yet another object is to so produce a springe nozzle having a rotatable spraying member that it can not cause injury during female douching.

A further object is to produce an efiicient syringe nozzle having a rotatable spraying member which will be economical to manufacture, easy to operate and quickly dismantled for cleaning purposes or for substitution of different size rotatable members.

Other objects of our invention will become apparent from the following description taken in connection with the accompanying drawings in which:

Figure l. is a longitudinal sectional View through a syringe nozzle shown by way of example as embodying our invention;

Figure 2 is an end view of the rotatable end member showing its surface shape;

Figures 3 and 4 are cross sectional views showing details of construction, said views being taken on the lines 3--& and 4-6, respectively, of Figure 1; and

Figure 5 is a longitudinal sectional view showinga modified rotatable spray member.

Referring to the drawings in detail, our disclosed improved syringe nozzle for use in female douching comprises a tubular body member where found desirable. Adjacentthe rear end of the tubular member there extends integrally therefrom a smaller tubular part or nipple H which is employed to conduct liquid to the conduit formed by the main tubular member. The tubular part I I is formed with a suitable knob end for connection with a flexible tube 112 comin from the cleansing liquid to be employed, which may comprise a receptacle such as a rubher bag. The tube l 2 is connected to the tubular part or nipple H by inserting the knob end as shown. The outer end of the tubular body member, beyond the point where the tubular extension Ii joins, is formed with an annular flange i3 providing a cylindrical recess [4 which is connected with the tubular body portion by a, passage 1 5. Mounted for rotation on the outer end of the tubular member is a knob 16 having a cylindrical projecting end I! for fitting into the cylindricalrecess and thereby providing a bearing and also a relatively leak proof joint. The knob is attached to an end of a flexible shaft l8 which extends through the tubular member ID and to the knob through passage l5. The knob can be attached to the shaft by having the shaft project into an axial bore l9 where it can be detachably held by a set screw 29. Other attaching means can be employed if desired.

The knob and flexible shaft are to be employed to rotate an elongated spray member 2! which is mounted on the inner end of the tubular member Ill. The rotatable member is closed at its outer end and formed with a smooth semi-spherical or similar rounded surface 22. The outer surface of its side wall is so formed as to be provided with elongated circumferentially spaced ridges 23 which also provide elongated valleys 24 therebetween. Both the tops of the ridges and the bottoms of the valleys between are smooth curves blending together. This construction thus produces an undulating or wavy outer surface. The spray member has an axial projecting portion 25 on its inner end which is of a diameter to fit into the outer lid of the tubular body member and be rotatable in said end. The spray member, including the projecting portion has an axial bore 25 into which is received the end of the flexible shaft IS. This end of the shaft and the spray member are permanently attached in any suitable manner. In surrounding relation to the shaft bore are a plurality of circumferentially spaced passages 2! closed at the outer end of the spray member and open at the inner end. These passages are so arranged that there will be a passage positicned inwardly and parallel with each 3 valley 24 on the outer side surface of thespray member. Spray orifices 28 connect each passage 2! with the exterior of the spray member at the bottom of the adjacent valley. The orifices may be of any number and, as shown, there are two spray orifices for each passage 21.

Since it is intended that the rotatable spray member is to rotate on a straight axis and the tubular body member is curved and also the flexible shaft extending therethrough, a bearing guide 29 is provided for the shaft adjacent the spray member to thereby cause this portion of the shaft to rotate on an axis at the outer end of the tubular member which will be aligned with the axis of. the rotatable spray member. As shown, the bearing guide is mounted slightly inwardly of the projection 25 on the rotatable spray member. It has an axial passage 3i] through which the shaft extends and bears. In surrounding parallel relation to the passage 38 are grooves 3| which provide passages through which liquid can flow from the tubular body 19 to the passages 2! in the rotatable spray member.

The rotatable spray member can be of other construction than that shown in Figures 1, 2 and 3. In Figure 5, for example, there is shown a modified construction wherein the rotatable member 2i having the semi-spherical end 22. ridges 23 and valleys 24' is hollow. The end has a bore 32 receiving the end of the flexible shaft which is suitably secured therein. Orifices 28' connect the hollow interior to the exterior at the valleys. The inner end of the member has an annular axially extending flange 33 which is received in the end of the tubular body member for rotative movement, thus providing a bearing 29 for the shaft sufficiently spaced inwardly from the end of flange 33 so there will be no interference with free flow of liquid to the rotatable spray member.

The operation of our improved nozzle is believed to be apparent from the description of the structure involved. The curvature is such that it will fit comfortably in the female cavity to be cleansed. When liquid flows through the tube I2 to the nozzle it .yvill pass through the tubular body member to the rotatable spray' member. Because of the orifices the liquid will be sprayed outwardly against the cavity walls and produce a washing. .During the spraying, knob [6 can be rotated, preferably in one direction of rotation and then in the opposite direction. The rotation of the knob will give like rotation to the spray member on the end of the tubular body member. This rotation will cause the ridges to move over the walls of the cavity and thereby straighten and open any folds or crevices so such can be efficiently washed by the jets of liquid coming through the orifices. The result will be a thorough cleansing action as all parts of the cavity walls will'be reached by the liquid. By having the spray orifices opening to the exterior surface of the rotatable spray member in the valleys between the ridges, the ridges will hold the walls of the cavity away from the orifices and permit free flow of liquid and further there will not be any danger of an outlet port edge of an orifice injuring the delicate membrane of the wall. It is also to be noted that the flexible shaft permits easy rotation of the spray member, notwithstanding the curvature of the tubular body member through which it extends. The bearing for the shaft adjacent the rotatable spray member insures that member will be rotated about a fixed straight axis and in a free manner without side thrusts. The construction of the nozzle permits it to be easily molded from a suitable material such as hard rubber or plastic substance. The construction also permits easy cleaning of all parts. When the knob is removed from the shaft by unloosening the screw, the rotatable spray member and shaft can be pulled out of the tubular body member. All sections of all parts can then be reached for cleaning. The construction also permits easy replacement of any worn or damaged parts. A different size rotatable spray member can also be substituted when found desirable. Several sizes of rotatable members can be sold with one tubular body member.

Being aware of the possibility of modification in the particular structure described as embodying our invention, without departing from the fundamental principles of the invention, we desire it to be understood that the scope of said invention is not to be limited in any manner except as set forth by the claimed structure or its equivalent.
